[tulip] Careful with Conexant LANfinity and 2.4

[Kent Hunt]

Donald,

	No lockups so far. But there is something
wrong with the TX_RING. I can easily get an
Out-of-sync drity pointer by doing an outbound scp
of a large file. The transfer then quickly gets
staled.
This doesn't happen with 2.2 kernels.

	Another thing that I noticed that is when I try to
remove tulip.o out of the kernel I get:
Trying to free nonexistent resource
<d09dc000-d09dc07f>
by /usr/src/linux/kernel/resource.c. This also doesn't
happen with 2.2 kernels.
	
	Kent
